I just bought a Jeep Patriot about 4 months ago. The brakes started squeaking when I back up last month. Now they squeak when applied going forward. I took the car into the dealer and was told "some vehicles brakes just squeak." Does not sound right to me. Is it?

My Jeep Patriot squeaks like an old mattress when I drive over a bump. I've recently put new shocks/break pads to the back & had trunk hinges replaced but the noise has yet to cease!!! What could it possibly be? I've read on jeeppatriotforum.com that other people had the same issue & said it was there emergency break cable.. Idk what to do

When I start my car, there is a squeaking sound coming from the drive belt. Is it rust? I recently replaced my alternator, could it be new parts against old parts making the squeaking sound? Then the noise settles, once car is warm. However, the squeaking sound is rapid and louder as I accelerate, then goes away as I come to a stop. Please advise?
